Wikipedia article for Charango
About 66 cm (26 in) long, the charango was traditionally made with the shell from the back of an armadillo (called quirquincho or mulita in South American Spanish),[3][4] but it can also be made of wood, which some believe to be a better resonator.
That's cool and all, but imma need assurances they died through natural causes.
